False alarms and bad GPS position
You're forced to open the app to see the alarm.
Then it won't work as the alarm was pushed to the entire country and their servers can't take any more requests.
When it finally works again, you see that the notified warning didn't even concern you as it's at the other end of the country.
I reported this issue months ago and it's still not fixed.
In addition, the position in the app is plain wrong by 10km so notifying 112 with your position would lead them to the wrong location.
